7. Unintelligible Nonsense Sign
We challenge you to read that sign and immediately understand what it is trying to say. If you succeed, congratulations! You are either clinically insane, or some kind of bizarre genius. We're going to take a completely uninformed crack at this one: While an audible or visual alarm is activated, please arrange for your imaginary friend to work together with the emergency services - this is the only way to survive the coming apocalypse. During this time of terrible strife, you should contact me, out of courtesy; I will be relaxing in a nearby reinforced cafe. We can't help but imagine this weird sign hanging on the wall in an Umbrella-style viral research lab, which will inevitably lead to a zombie outbreak, due to sub-par security.
